Hi,
I got my installation working well until I decided to update RedHat EL 4 online.
Now my zimbra LDAP server is not working, I tried reinstalling it (just LDAP and core) but it gives the error:

ERROR: service.FAILURE (system failure: getDirectContext) (cause: javax.naming.CommunicationException zimbra4.mailweb.ufm.edu.gt:389)

Could someone help me ?
Thanks.
